Application filed October 24, 1893.: Serial No. 489,007. on; model.)

My invention relates particularly to the method of securing the running gear to a stone crusher and combining with it, in a convenient manner, a suitable elevator for elevating the crushed material to a screen and v p removing the same from the frame-and doing 1 chute for the proper sorting of the same.

- It has for its objectthe providing of a simple, economicaland efficient portable stone crusher; and my invention consists in the features, details and combinations hereinafter described and claimed. I

In the drawings, Figure 1 is a side elevation of my improvement; Fig. 2 a plan view,

looking at the same from the top, and Fig. 3

a. sectional elevation of a portion of the meohanism, taken on line 3 of Fig. 2 looking in the direction of the arrow.

In the construction of my'improvementfl prefer to use an ordinary stone crusher, A, of the type known as thegyrating crusher, said crusher frame being provided with the usual discharge openinga, for the discharge of the crushed material',and three other openings, B, B and B looated at equi-distant points around thecircumference and intended primarily for the insertion of the mechanism for operating the crushing mechanism.

' Secured to the frame at and in line with. the opening, B, is a'jsupporting frame or bracket, 0, provided with hearings in which; is mounted a driving shaft, c, which is provided at its inner end with a gear engaging with and adapted to rotate, the ;beveled gear which actuates the crushingmechanism, and also provided with a pulley, 0, adapted to be operated by a beltvfrom some suitable motor. This frame, 0, is so constructed that it is adaptedto be secured at one end only to the crusher frame, by means ofsuitable nuts and bolts, and has its lower surface practically fat and constructed in such manner that there may be detachably secured to it a metallic brace or bracket, D, extending forward and downward to be pivotaliy engaged with usual manner a-pair of Wagon wheels, (1',

thill' coupling, axle tree and tongue. The mounting of the wheels in the above described manner provides a mininilim amount of gearing, and allows the gearing to make a suitable turn in rounding corners. I

cured to the crusher frame independently of each other, for the purpose of more readily away with the usual axle in suchcases proinsertion of the driving gear. To accomplish this result, I provide hubs, G, having a portion, g, of suitable diameter to snugly fit bolts and nuts, g, in such manner that the hub may vbeeasilyremoved when desired.

nor to that portion of the hub, preferably geons, H, and on these gudgeons I mount in any convenient manner the wheels, E, so that they may easily rotate during the moving of the crusher from place to place, and which is particularly illustrated in Fig. 3 of the drawings." I

When it is desired to usethe crusher as a stationary crusher, the hubs, G, may be removed, which action removes also the wheels,

or hounds, D, are also removed, thereby re: moving the front running gear and allowing the crusher to be placed'on a suitablefoundation and used as a stationary crusher. itis used as a portable crusher, it is someapparatus attached to it, and means for eleas it passes out of the discharge opening to thescreen. To accomplish. this result, I provide beams, I,-which may be attached to and entirely supported by the crusher frame-- provided with suitable bearings, in which is mounted near the top a shaft, t, provided at near the lower portion of the opening, gud-- E, and by removing the bolts, (1 the brace When times desirable to have a suitable screening an' axle,d, upon which is mounted in the preferably constructed upon the bicycle type. I This axle may be provided with the usual The side wheels, E, are mounted and sevided, and to make use of the holes in the frame which are at right angles to the discharge chute and primarilyintended for the 1 the bore of the openings, B and ;B and secure the hub to the frame by m'ans of the I mount securely 1n any convenient manvating the material after it has been crushed .IOO

. one end with a pulley, 'i', and near its center,

between the side beams, with a pulley, E intended for supporting and driving the belt, K, carrying the elevator buckets, k.

Near the lower end of the side beams is mounted in suitable bearings a shaft, L, which carries a pulley, 1, around which the elevator belt and buckets pass, in such manner as to bring them close to the discharge chute, a, of the crusher.

The elevator mechanism is driven preferably through the mechanism which operates the crusher head, and in the following manner: Mounted in one of the hubs, G, shown particularly in Fig. 3, is a hollow shaft, M,

having at its inner end a beveled pinion, m,

engaging withand adapted to be operated by the rotation of the beveled gear, m, which actuates the gyrating shaft, m end the hollowshaft is provided with a shoulder, m and bears against the hub to limit the longitudinal motion of the hollow shaft. A shaft, N, enters the axial opening of the hollow shaft, and is engaged with it bymeans of a feather, 'n, and corresponding feather way, so as to impart the rotations of the hollow shaft to the shaft, N, and permit it,

throu h its ulley n1 to impart the necessary rotation to the elevator mechanism bymeans of the belt, 02 through the shoulder of the hollow shaft and impinges against the shaft, N, to prevent the 1 same having any longitudinal motion during its rotation, and at the same time, when the set screw is slackened, to allow the shaft, N, to be withdrawn from engagement with the hollow shaft.

It will be observed that the shaft, N, is

passed through the spokes of one of the wheels, E, when it is necessary to operate the elevator, and that consequently such wheel could not be rotated or the crusher moved from place to place.

The easy removal of the shaft by the means a above described permits the wheel, E, to turn and the mechanism to be movedfrom place to place.

A chute, O, is secured to the side beams which form the elevator frame in any convenient manner, preferably by means of hinges, 0, and supported by a chain, 0, at its outer end secured to the elevator frame. The lower plate 0 of the screen, along which the crushed material passes after it is dumped on the same from the elevator, is made of reticulated material, or a wire screen, of any desired gage, for screening the crushed mate- At the outer A set :screw, n is passed rial and at the same time acting as a chute to deliver the material so screened to any desired point.

While I have described the intermediate mechanism which is mounted on the hollow shaft with great minuteness, I do not desire to claim the same, as it forms no part of my invention. Neither do I lay any claim to the crushingmechanism or methods used in driv ing the same.

I claim-- 1. Inportable stone crushers, the combination of a crusher frame provided with suitable crushing mechanism and openings located around the circumference of the frame, mechanism adapted to be secured to the frame at and in line withtwo of such openings for the mounting of wheels forming the running gears, and wheels rotatably mounted on such mechanism, substantially as described.

2. A portable stone crusher, comprising a crusher frame provided with suitable crushing mechanism and openings located around the circumference of the frame, a bracket for carrying the actuating mechanism of the for the insertion of actuating mechanism, a

bracket for carrying the actuating mechanism secured to the crusher frame at and in line with one of its openings, running gear adapted to be secured to such bracket,means for removably securing such running gear and bracket, wheels forming a portion of the running gear independently secured to 'the crusher frame at and in line with the side openings, means for securing such independently to the crusher frame at and in line with such openings, an elevator for raising the crushed material to a desired point, and a combined screen and chute for screening the crushed material after it has been raised, substantially as described.
